The Citation II was developed from the Citation I. The Citation II has a longer cabin than the Citation I, by making the seating capacity ten passengers. Cessna’s goal was to compete in the turboprop market with a jet that seats ten. The Citation II is single pilot capable and is a very popular aircraft on the charter market due to its large seating capacity and efficient operating costs. Charter operators love the Citation II for its efficiency and simplicity. The Citation II has an aft lav and great short runway performance due to its straight wing design. The Citation II later developed into the Citation V and is now the Citation Encore today.
